'''Chameleon Whip''':
Wait, if whips are fallout weapons, why is there a whip in the high tier category? It's because the magical abilities they hold. The chameleon whip has the chance to polymorph most enemies it hits. Although this is initially considered a weapon to avoid despite its high stats (usually 3-6 when made of ommel hair), the value of turning a pesky veteran dark knight into a harmless spider in invaluable. When made into golden eagle feather, it packs a serious punch that can hit enemies multiple times before they have a chance to strike back. The incredible lightness helps blocking capabilities as well. Can be cloned too, theoretically doubling the chances of polymorphing your enemy when dual wielded.
'''Flaming Sword''':
A jack of all trades sword-except it's on fire. What's not to like? Not only does it serve as a permanent light source, the sword will also burn enemies on contact, providing one of the few sources of unblockable, unresistable damage in the game. The roundness and the lightness are strong together, and they can easily be wielded in one hand, and since they aren't artifacts, can be cloned, meaning you only have to focus on one, then make another rocking flaming valpurium sword+10 (wait...)
